Abstract: A method and apparats for undervoltage detection and correction is disclosed. An IC includes sensors implemented in various functional circuit blocks. The sensors are implemented using ring oscillators, and may be characterized by a polynomial. The sensors are used to monitor a supply voltage provided to a corresponding functional unit. The sensors provide information indicative of the voltage on the supply voltage node over successive clock cycles. Comparison circuitry may be used to compare the detected voltage to one or more voltage thresholds, while delta comparison circuitry may be used to determine a slope, or rate of change of the voltage. Based on comparisons performed by the comparison circuitry and the delta comparison circuitry, control circuitry may determine if one or more voltage correction actions are to be taken in order to bring the voltage on the supply node into a specified range.

Abstract: In an embodiment, a system includes multiple power management mechanism operating in different time domains (e.g. with different bandwidths) and control circuitry that is configured to coordinate operation of the mechanisms. If one mechanism is adding energy to the system, for example, the control circuitry may inform another mechanism that the energy is coming so that the other mechanism may not take as drastic an action as it would if no energy were coming. If a light workload is detected by circuitry near the load, and there is plenty of energy in the system, the control circuitry may cause the power management unit (PMU) to generate less energy or even temporarily turn off. A variety of mechanisms for the coordinated, coherent use of power are described.

Abstract: An inductor is disclosed, including a first wire, a non-conductive material, and a shell. The non-conductive material may cover the first wire, with a portion of each end of the first wire uncovered. The shell may include a top portion and a bottom portion and include at least one magnetized layer and at least one gap between the first portion and the second portion. The shell may also surround a portion of the non-conductive material.

Abstract: In one embodiment, an integrated circuit includes a power management architecture in which one or more pipelines are actively powered and clocked when data is provided for processing, but which are clock gated and in retention when there is no data to be processed. When data is provided to the pipeline, supply voltage may be actively provided to initial stages of the pipeline and the clocks may be ungated when the voltage is stable enough for operation. Subsequent stages of the pipeline may be sequentially provided power and clocks as the data progresses through the pipeline. Initial stages may be clock gated and power may be deactivated when additional data is not provided for processing. Accordingly, when the pipeline is viewed as a whole, power may be seen as rolling forward ahead of the data processing, and power may be inhibited in a similar rolling fashion.
